Pokopia Paper, Concrete & Control Unit Guide

How to get Paper, Concrete, and the Control Unit in Pokémon Pokopia. Wastepaper, Limestone, specialty requirements, mixer setup, and the best pickup locations.

Author: Pokopia Guide Team

If you are in mid-to-late game progression, three materials constantly slow building projects down: Paper, Concrete, and the Control Unit. They are all tied to specific areas or processing methods, so they are easy to miss even if you already have the required Pokémon. This guide collects the fastest confirmed ways to get all three.

Fast Answer

  • Paper: give Wastepaper to a Pokémon with Recycle Recycle
  • Concrete: place a Concrete Mixer near water, add Limestone, then use a Crush Crush Pokémon
  • Control Unit: find one in Sparkling Skylands abandoned buildings / eastern island area, or craft one once you have the recipe

How to Get Paper

Paper is a processed material, not a direct pickup.

Step 1: Find Wastepaper

The raw material for Paper is Wastepaper.

Current confirmed source:

  • pick it up around Sparkling Skylands

Wastepaper also appears in broader Sparkling Skylands resource loops, so it is worth grabbing even if you are not ready to process it yet.

Step 2: Use a Recycle Recycle Pokémon

Give Wastepaper to a Pokémon with the Recycle Recycle specialty. Confirmed examples on the site:

If you are already preparing the Porygon habitat, this is a good place to overlap your farming route.

How to Get Concrete

Concrete is one of the most important progression materials in late-game construction.

Step 1: Craft the Concrete Mixer

Before you can make Concrete, you need a Concrete Mixer.

  • recipe source: Conkeldurr during the Sparkling Skylands story
  • crafting note: the mixer itself needs 2 Iron Ingots

Step 2: Place the Mixer Near Water

The Concrete Mixer only works when it is placed near water. If you set it down in the wrong location, your Crush Pokémon will not be able to process the material properly.

Step 3: Add Limestone and Use a Crush Crush Pokémon

Concrete is made by adding Limestone to the Concrete Mixer and bringing over a Pokémon with the Crush Crush specialty.

Good confirmed Crush options include:

Where to Find Limestone

Confirmed sources:

  • Sparkling Skylands — the main best source, with large numbers of striped white blocks
  • Rocky Ridges hot spring cave — a secondary large deposit
  • Dream Island / Rock Peak — useful if you are already farming there

If you are building in bulk, Sparkling Skylands is still the main route to optimize first.

Why Concrete Matters

Concrete is used heavily in progression and construction. Based on current site data:

  • 50 Concrete is needed for the Team Initiation Challenge
  • 25 Concrete is needed for the Sparkling Skylands Pokémon Center

That is why Limestone farming becomes a bottleneck so quickly.

How to Get the Control Unit

The Control Unit is a special component rather than a common crafting material.

Confirmed ways to obtain it:

  1. Find one in Sparkling Skylands, in the abandoned building / eastern island area
  2. Craft one after unlocking the recipe

Crafting requires:

  • Pokemetal ×1
  • Glass ×1
  • Iron Ingot ×1 or ×2 depending on source listing

The fixed overworld pickup is still the safest early route if you only need one for habitat progression.

What the Control Unit Is Used For

The Control Unit is required for the Factory Storage habitat used for Porygon. To complete that setup, you also need:

  • Metal Drum
  • Jumbled Cords
  • Streetlight

It is also used in some later crafting setups, so do not treat it like a disposable one-off pickup.

Best Farming Order

If you need all three materials in the same stage of the game, this is the cleanest order:

  • Go to Sparkling Skylands
  • Pick up the Control Unit from the town building
  • Collect Wastepaper
  • Break Limestone while you are still in the area
  • Return to base and process:
  • Wastepaper with Recycle Recycle
  • Limestone with the Concrete Mixer + Crush Crush

This reduces travel and lets one area feed multiple bottlenecks at once.

Quick Tips

  1. Do not wait until a build asks for Concrete — stockpile Limestone early.
  2. Set up one Recycle Pokémon and one Crush Pokémon near storage.
  3. Sparkling Skylands is the best overlap zone because it gives you Control Unit, Wastepaper, and Limestone progress in one route.
  4. Craft the Concrete Mixer as soon as Conkeldurr unlocks it.
  5. Keep spare Control Units if future advanced builds continue using them.
